Node.js

What is it?

Node.js is an open-source, cross-platform JavaScript runtime that allows developers to run JavaScript on the server. It uses an event-driven, non-blocking I/O model optimized for scalability.

What does it do?

Node.js enables building fast backend services, APIs, and real-time systems. Its asynchronous architecture efficiently handles concurrent requests, making it suitable for high-traffic and I/O-heavy applications.

Where is it used?

Node.js is widely used in SaaS platforms, REST and GraphQL APIs, real-time applications, microservices, streaming services, and serverless architectures.

When & why it emerged

Node.js was introduced in 2009 by Ryan Dahl to address performance limitations of traditional server models. It emerged to handle many simultaneous connections efficiently using a single-threaded event loop.

Why we use it at Internative

We use Node.js to build scalable backend systems and real-time services. Its performance, rich ecosystem, and alignment with modern frontend stacks make it ideal for full-stack and SaaS architectures.
